What is wrong with this PC?

Nothing I can think of. Its a pretty good deal actually, considering it comes with wi-fi, bluetooth, and 6 and 1 card reader too. I tried specing out the same on Newegg and ended up hitting about $850, probably more than that since I didn't include wifi, bluetooth, and 6 in 1 card reader. My immediate wonders though are the quality of the power supply, and what gtx 760 out there has 3 GB of video RAM?
 


Yeah... I'd assume a subpar PSU on pre-builts too. Also, I'm not even 50% sure but those dimensions seem a tad small and could limit possible future upgrades.
